.To all whom t may concern.'

Be it known that I, DANIEL II. HOLLINGS- WORTH, of the city of Brooklyn, county of Kings, and State of New York, have invented a new and useful Improvement in Street- Sweepers, of which the following is a spcciiication.

The object of my invention is to provide a street-sweepercapable of workin gin conj unction with an ordinary dirt-cart, whereby the sweepings of the street are automatically raised and deposited in the saiddirt-cart.

In the accompanying drawings, Figure l is a longitudinal section of a streetsweeping apparatus constructed according to my invention, and showing a cart attached thereto. Fig. 2 is a sectional plan taken at the plane of the line v 0o, Fig. l; and Fig. 3 is atop View of a guide-plate employed in the machine.

a designates a casing supported upon a rotary axle Z) of a pair of wheels b b2 and upon the axle c of a pair of wheels c c2. The said casing may be of any suitable material and construction. It is provided with a receptacle a for the sweepings of the broom and an extension a2, adapted in height and length to admit of an ordinary dirt-cart being pushed beneath it. The axle c is mounted in the arms c3 c4 ofacross-bar c5, which has a swiveling connection by means of an ordinary fifthwheel c with abar c7, extending forward from the casing and rigidly secured thereto by angle and brace bars e8.

d is an ordinary broom secured on a shaft d', the latter being carried in arms d2 d3, whose ends are loosely mounted. on the axle b, journaled in the sides of the casing.

(Z4 d5 are links connecting the extremities of the arms (Z2 cl3 and the ends of a cross-bar d6, the latter forming a part of a T-shaped lever (Z7, journaled to rock in a bearing d8. This lever is provided with a handle d, arranged within reach of the driver and capable of being secured in a hook d when the broom is not in use.

Motion is imparted to the broom by means of a sprocket-chain e, passing around a Wheel e4, secured on the shaft d', and driven by a sprocket-wheel e', secured to a shaft e2, the latter being j ournaledin the sides of the casing. The chain e extends around a wheel e, secured to a shaftf, mounted in bearings secured to the sides of the casing.

This shaft has rigidly sesprocket-wheelf, which imparts motion to a pair of chains f 3 f4, having buckets f5 rigidly secured thereto. The chains are led over guide-wheels f, arranged at the end of the extension a2, after passing over guide-wheels f7. From the wheels f the chains are led to wheels f8, around which the buckets are carried to receive the dirt deposited in the receptacle a. The buckets are then elevated and passed along the extension a2 to the wheels f6, and in passing around which the contents of the buckets are free to fall and pass through an opening a3 in the casing into the dirt-cart.

Motion is imparted to the shaft e2 by a gearwheel g, secured on the axle b, and engaging a gear-wheel gQ loosely mounted on the shaft e2. The gear-wheel g has on one side clutchteeth to engage with corresponding teeth of a clutch-collar g4, fitted to slide on a spline attached to the shaft e2.

h is a lever fulcrumed to a bracket 7L and having a bifurcated end to engage in an annular groove g around the collar g4. The lever h extends diagonally upward to a position within reach of the driver, who can thereby disconnect the moving parts within the casing from the axle when desired.

The dirt from the broom is carried against and up a movable guide -plate 2'., which is mounted to'swing on a bar c", supported in the sides of the casing a. The plate t is provided with perpendicular side portions 2, which converge toward each other from the rear of the apparatus in order to compress the bristles of the brush at its two ends and so prevent the tendency of the dirt to pass to one side instead of against the guide-plate and from thence into the receptacle a. By this means the broom leaves no ridges of dirt sidewise of it as it passes along.

t4 t5 are chains connecting the free ends of the guide t' to the arms d2 d3, whereby the plate t' partakes of the upward and downward movements of the broom.

The sweeping apparatus is connected to the dirt-cart, to be drawn along a street therewith by any suitable means. As here shown this is effected by chainsj, arranged one on each side of the cart, and which are attached to sta- IOC) ples or standards j', secured to the endsof the cross-bar. The opposite ends of the chains may be passed through staples j?, secured to the sides of the cart and hooked to one of the links composing the chain. The Wheels c c2 are so proportioned in diameter and distance apart as to admit of the Wheels of the cart passing freely outside of the same and With sufficient clearance to enable the cart to turnl to some extent around the same.
